An 18th-century map and print seller, who worked in London from about 1714, producing some of the best and attractive maps of the century. A recurring feature of Bowen's work, evident even on the early road maps, was his habit of filling every corner and space of the map with jottings and footnotes, both historical and topographical.
One of his earliest engraved works, Britannia Depicta, published in 1720, contained over two hundred road maps together with a miniature county map of each of the counties of England and Wales. It was an unusual feature of the atlas that the maps were engraved on both sides of each page, and this resulted in a handier-sized book.
He also issued with John Owen a book of road maps based, as was usual at the time, on John Ogilby but again incorporating his own style of historical and heraldic detail.
In spite of his royal appointments and apparent prosperity he died in poverty and his son, who carried on the business, was no more fortunate and died in a Clerkenwell workhouse in 1790.
He published "A Complete System of Geography, 1744-7; an 'English Atlas, with a new set of maps,' 1745(?); a 'Complete Atlas ... in sixty-eight Maps,' 1752; 'Atlas Minimus; or a new set of Pocket Maps,' 1758; and a series of separate maps of the English counties, of Germany, Asia Minor, and Persia, between 1736 and 1776.
Complete map of the Southern Continent
Bowen's map, A Complete Map of the Southern Continent survey'd by Capt. Abel Tasman & depicted by order of the East India Company in Holland in the Stadt House at Amsterdam, was essentially a copy of the map Melchisédech Thévenot had published in Relations de divers Voyages curieux (Paris, 1663, v.1). Although Thévenot said that he had taken his chart from the one inlaid into the floor of the Amsterdam Town Hall, it appears to be an almost exact copy of that of Joan Blaeu in his Archipelagus Orientalis sive Asiaticus published in 1659 in the Kurfürsten Atlas (Atlas of the Great Elector). The map of the world set into the floor of the great hall of the Amsterdam Town Hall was drawn from Blaeu's world map of 1648. Once Blaeu's map of the world appeared other mapmakers, such as Thévenot, copied his depiction of New Holland. Hollandia Nova in the Kurfürsten Atlas is shown as it appears in Blaeu's world map of 1648. It appears to have been Thévenot who introduced a differentiation between Hollandia Nova to the west and Terre Australe to the east of the meridian corresponding to 135° East of Greenwich, emphasised by the latitude staff running down that meridian, as there is no such division on Blaeu's map.
A legend on Bowen's map emphasised the separation between Hollandia Nova and Terra Australis that had been introduced either inadvertently or intentionally by Thévenot when he placed the two names on either side of the latitude staff running down the 135° East of Greenwich meridian. Bowen's map legend identified Terra Australis as the land described by Quirós by saying:
It is also requisite to observe that the Country discovered by Ferdinand de Quiros lies according to his description on the East Side of this Continent directly opposite to Carpentaria which if Attentively considered will add no small weight to the Credit of what he has written about that Country and which has been very rashly as well as very unjustly treated by some Critical Writers as a Fiction; Whereas it Appears from this Map of Actual Discoveries, that there is a Country where Ferdinand de Quiros says he found one: And if so why may not that Country be such a one as he describes?
Another legend added by Bowen to the map called for discovery and settlement of Terra Australis:
It is impossible to conceive a Country that promises fairer from its Situation than this of TERRA AUSTRALIS, no longer incognita, as this Map demonstrates, but the Southern Continent Discovered. It lies precisely in the richest climates of the World....and therefore whoever perfectly discovers and settles it will become infalliably possessed of Territories as Rich, as fruitful, and as capable of Improvement, as any that have hitherto been found out, either in the East Indies or the West.
The territorial claim made by Britain when the colony of New South Wales was established in 1788 included all of Australia eastward of the meridian of 135° East dividing New Holland from Terra Australis, as shown on Bowen's map.
